NASA is calling it the interplanetary Internet, and announcements
have been hitting in recent weeks regarding the sending of the first
emails, voicemails and, of late, news of an experiment that involved
remote controlling of a LEGO space robot with it. But what’s truly cool
is the technology enabling it — it’s a protocol called Delay-Tolerant
Networking, better known as DTN.

At its heart is Vint Cerf’s Bundle Protocol (BP), a version of the IP
protocol he helped develop to pioneer the Internet decades ago.
